Description

Technical Field

[0001] This invention relates to the field of edible fungi cultivation technology, specifically to a constant temperature cultivation device for edible fungi production with temperature control regulation. Background Technology

[0002] The cultivation of edible fungi relies on precise environmental control, with temperature being a core factor affecting mycelial growth, fruiting body differentiation, yield, and quality. Constant-temperature cultivation devices are crucial equipment for the industrialized production of edible fungi. Maintaining a stable temperature environment while shortening the cultivation cycle is fundamental to achieving large-scale, standardized production of edible fungi. However, existing devices are prone to temperature gradients during temperature control, leading to significant differences in maturity times among fungi inoculated from the same batch, impacting harvesting efficiency. To address these shortcomings, a constant-temperature cultivation device for edible fungi (publication number CN219305590U) uses a temperature sensor to detect the temperature inside the chamber, which is then relayed to a control mechanism. This control mechanism activates electric heating elements and an airflow fan to regulate the internal temperature. However, in this solution, when hot air is blown into the constant-temperature cultivation device using the electric heating elements and fan, temperature differences exist between fungi at the edges and corners and those in other locations, resulting in variations in maturity times within the same batch. Summary of the Invention

[0003] The purpose of this invention is to provide a constant temperature cultivation device for edible fungi production with temperature control regulation, so as to solve the problem that when the existing constant temperature cultivation device for edible fungi production blows hot air into the constant temperature cultivation device with electric heating tubes and fans during temperature control, there is a temperature difference between the edible fungi at the corners and the edible fungi in other positions, which causes the same batch of edible fungi to mature at different times.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a constant temperature cultivation device for edible fungi production with temperature control, comprising a box body, a sealing door and a controller at the front of the box body, a temperature sensor installed at the top of the box body, and support plates for placing edible fungi culture vessels evenly spaced inside the box body; an air jet pipe is provided above the support plate, the left end of the air jet pipe is movably connected to the left side wall of the box body, and a swinging component is provided in the left side wall of the box body, the swinging component being used to drive the air jet pipe to move back and forth and swing around its own axis, thereby uniformly spraying air onto the support plate; an air guiding mechanism is provided on the support plate, the air guiding mechanism causing hot air to diffuse evenly inside the box body.

[0005] Furthermore, the swing assembly includes a lead screw, a slider, a gear, a rack, and a linkage drive mechanism. The number of lead screws is the same as the number of jet pipes and they correspond one-to-one. The lead screw is rotatably connected to the left side wall of the housing. A slider is threaded onto the lead screw and is slidably connected to the left side wall of the housing. The gear is rotatably connected to the slider and a torsion spring is between them. The left end of the jet pipe is fixedly connected to the gear. The rack is fixed inside the left side wall of the housing and has intermittently arranged teeth. The linkage drive mechanism is located on the left side wall of the housing and is used to drive the synchronous rotation of the lead screw.

[0006] Furthermore, the swing assembly includes a lead screw, a slider, a swing drive mechanism, and a linkage drive mechanism. The number of lead screws is the same as the number of jet pipes and corresponds one-to-one. The lead screw is rotatably connected to the left side wall of the housing. A slider is threaded onto the lead screw and slidably connected to the left side wall of the housing. The swing drive mechanism includes a swing motor and gears. The number of gears is the same as the number of lead screws and corresponds one-to-one. The gears are rotatably connected to the sliders on the corresponding lead screws. The gears on every two adjacent sliders are externally meshed. The swing motor is located on one of the sliders and drives the gear on that slider to swing. The linkage drive mechanism is located on the left side wall of the housing and is used to drive the synchronous rotation of the lead screw.

[0007] Furthermore, the linkage drive mechanism includes a moving motor and a sprocket mechanism. The moving motor is fixed on the housing and its output shaft is fixedly connected to a lead screw located in the middle. The middle lead screw is connected to other lead screws through a sprocket mechanism.

[0008] Furthermore, the jet pipe is connected to a hot air blower via a connecting pipe, and the hot air blower is located inside the left side wall of the housing.

[0009] Furthermore, the air guiding mechanism includes a spiral guide plate, and the bearing plate has through holes arranged at equal intervals, with the guide plate located within the through holes.

[0010] Furthermore, it also includes a spacing adjustment mechanism, which includes a rotating rod, a pull rope, a pin, and a spring. The rotating rod is rotatably mounted at the front center of the support plate. A pull rope is wound around the rotating rod, and pins are fixed at both ends of the pull rope. The pins are slidably connected to the support plate, and a spring connects the two. The side wall of the box has a slot that engages with the pin. When the pin is inserted into the slot, the support plate and the box are relatively fixed.

[0011] Compared with the prior art, the beneficial effects of the present invention are: When in use, the invention uses the reciprocating movement of the jet pipe combined with the back-and-forth swinging motion to evenly deliver hot air to the edible fungus incubator on the support plate. The airflow is further diffused by the guide plate to even out the temperature inside the chamber. The position of the support plate can also be adjusted as needed.

[0012] 1. The slider on the lead screw slides back and forth along the groove. When the slider moves, the gear on the jet pipe meshes intermittently with the rack on the left side wall of the box, so that the jet pipe swings synchronously when it moves back and forth, so that the hot air sprayed by the jet pipe can evenly cover the edible fungus incubator on the support plate. The dispersion / diffusion of hot air avoids the temperature at the corners being too low and balances the temperature field inside the box.

[0013] 2. The through-hole has a built-in spiral guide plate. When hot air passes through the through-hole, the guide plate guides the airflow to form a spiral upward airflow, breaking the airflow stratification between layers and making the temperature of the upper and lower layers tend to be consistent.

[0014] 3. When rotating the rod, the pull rope pulls the pin to compress the spring, causing it to disengage from the slot on the inner wall of the box, and then the height of the support plate can be adjusted; after releasing the rod, the spring returns to its original position and pushes the pin to re-engage and fix the position of the support plate. The adjustable height of the support plate is designed to adapt to edible fungi at different growth stages. Attached Figure Description

[0017] like Figures 1 to 6As shown, the present invention includes a housing 1, a temperature sensor 3, a swing assembly, a jet pipe 9, a hot air blower 11, a support plate 13, a flow guiding mechanism, and a spacing adjustment mechanism. The structure and working principle of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] like Figures 1 to 3 As shown, a constant temperature cultivation device for edible fungi production with temperature control includes a box body 1. A sealing door 2 and a controller are located on the front side of the box body 1. A temperature sensor 3 is installed on the top of the inner cavity of the box body 1. A support plate 13 for placing edible fungi culture vessels is arranged inside the box body 1. Multiple support plates 13 are arranged at equal intervals vertically within the box body 1. Air jets 9 are slidably arranged at equal intervals on the left side wall of the box body 1, positioned above the support plate 13. A swing assembly and a hot air blower 11 are located on the left side wall of the box body 1, connected to the air jets 9 via a connecting pipe. Hot air generated by the hot air blower 11 enters the air jets 9 through the connecting pipe and is then ejected through nozzles on the air jets 9. The swing assembly, located inside the left side wall of the box body 1, drives the air jets 9 to reciprocate along the front-to-back direction of the box body 1 and to swing around their own axis. An air guide mechanism is provided on the support plate 13, causing the hot air to be evenly distributed vertically within the box body 1.

[0019] In use, the entire device is supported by housing 1. The controller sets the target temperature, and temperature sensor 3 monitors the internal temperature of housing 1 in real time. If the temperature falls below the set value, the hot air blower 11 starts. Figures 2 to 3 As shown, the jet pipe 9, driven by the oscillating assembly, performs a reciprocating and oscillating motion, uniformly jetting hot air during the movement to evenly deliver it to each layer of the support plates 13. The hot air is further diffused by the air guide mechanism on the support plates 13, ensuring a consistent temperature in the edible fungus cultivation environment and creating a uniform temperature field within the chamber 1. Figures 2 to 3 As shown, the height of the support plate 13 can be adjusted to meet the growth requirements of edible fungi, thereby shortening the time difference in maturity of the same batch of edible fungi, significantly improving cultivation efficiency and quality. Through the linkage of mechanical transmission and intelligent control, a closed-loop process of "temperature measurement - temperature control - temperature uniformity" is formed, solving the problem of uneven temperature field in traditional devices.

[0020] The oscillating component drives the jet pipe 9 to move back and forth, while also causing it to oscillate, ensuring that hot air is evenly delivered to the edible mushroom incubator 21, allowing the same batch of edible mushrooms to mature at approximately the same time. Figures 2 to 4As shown, the specific structure of the swing assembly is as follows: The swing assembly includes several lead screws 5 arranged at equal intervals. Slide grooves 6 are equally spaced on the left side wall of the housing 1. The lead screws 5 are located within the slide grooves 6 and are rotatably connected to the left side wall of the housing 1. In this embodiment, three lead screws 5 and three layers of bearing plates 13 are provided. The rear end of the middle lead screw 5 is fixedly connected to the output shaft of the moving motor 4, which is mounted on the rear side wall of the housing 1. The upper and lower lead screws 5 are connected to the middle lead screw 5 via a sprocket mechanism, thus enabling the several lead screws 5 to move in tandem. The sprocket mechanism and the moving motor 4 constitute a linkage drive mechanism, which drives the several lead screws 5 in tandem. A slider 7 is threaded onto the lead screw 5. The slider 7 slides in conjunction with the slide groove 6. A gear 8 is rotatably connected to the slider 7, and the gear 8 is fixedly connected to the left end of the corresponding jet pipe 9. When the lead screw 5 rotates, it drives the slider 7 to move back and forth, thereby driving the jet pipe 9 to move back and forth. A torsion spring 10 is installed at the connection between gear 8 and slider 7. A rack 12 is fixed on the left side wall of housing 1. The number of racks 12 is the same as the number of lead screws 5 and corresponds one-to-one. The racks 12 are parallel to the corresponding lead screws 5. The racks 12 have teeth arranged at intervals, that is, the teeth on the racks 12 are set intermittently. Gear 8 and rack 12 mesh intermittently. When the lead screw 5 rotates, it drives the slider 7 to move back and forth. When the slider 7 moves, it drives the gear 8 to move synchronously. During the movement of gear 8, after gear 8 meshes with the teeth on rack 12, rack 12 drives gear 8 to swing. At this time, torsion spring 10 is compressed, and gear 8 swings while moving back and forth with slider 7. When gear 8 separates from a section of teeth on rack 12, gear 8 returns to its original position under the action of torsion spring 10 until gear 8 meshes with the next section of teeth on rack 12. Then torsion spring 10 is compressed again, and gear 8 swings again.

[0021] During use, the moving motor 4 drives the central lead screw 5 to rotate, which in turn drives the upper and lower lead screws 5 to rotate synchronously / interlock through the sprocket mechanism. Figures 2 to 3 As shown, the slider 7 on the lead screw 5 slides back and forth along the groove 6, causing the jet pipe 9 to move synchronously, expanding the coverage area of ​​the hot air. When the slider 7 moves, as... Figure 4 As shown, the gear 8 on the jet pipe 9 intermittently meshes with the rack 12 on the left side wall of the housing 1, causing the gear 8 to oscillate intermittently. During the oscillation, the torsion spring 10 stores energy. After the gear 8 disengages from the rack 12, the torsion spring 10 resets, causing the gear 8 to oscillate in the opposite direction, which in turn causes the jet pipe 9 to oscillate back and forth. Through the combined motion of reciprocating movement and oscillation, the hot air ejected from the jet pipe 9 can evenly cover the edible fungus incubator 21 on the support plate 13, preventing the temperature at the corners from being too low.

[0022] The swing assembly can also have other structural forms. For example, the swing assembly includes several lead screws 5 arranged at equal intervals, and grooves 6 are equally spaced on the left side wall of the housing 1. The lead screws 5 are located in the grooves 6 and are rotatably connected to the left side wall of the housing 1. In this embodiment of the invention, three lead screws 5 and three layers of bearing plates 13 are provided. The rear end of the middle lead screw 5 is fixedly connected to the output shaft of the moving motor 4, and the moving motor 4 is installed on the rear side wall of the housing 1. The upper and lower lead screws 5 are connected to the middle lead screw 5 through a sprocket mechanism, so that several lead screws 5 can achieve linkage action. The sprocket mechanism and the moving motor 4 constitute a linkage drive mechanism, which is used to drive the linkage action of several lead screws 5. A slider 7 is threadedly connected to the lead screw 5. The slider 7 slides in the groove 6. A gear 8 is rotatably connected to the slider 7, and the gear 8 is fixedly connected to the left end of the corresponding jet pipe 9. A swing motor is fixed on one of the sliders 7. The output shaft of the swing motor is fixedly connected to the gear 8 on the slider 7, thereby driving the gear 8 on the corresponding slider 7 to swing. The gears 8 on each pair of adjacent sliders 7 mesh externally, so that when the oscillating motor drives the gear 8 on the corresponding slider 7 to oscillate, the other gears 8 oscillate synchronously.

[0023] The air guiding mechanism ensures that the blown hot air is evenly diffused during transport, further improving temperature control. For example... Figures 2 to 3 and Figure 5 As shown, its specific structure is as follows: The air guiding mechanism includes a guide plate 15, and through holes 14 are equally spaced on the bearing plate 13, with a spiral guide plate 15 installed in the through holes 14. Figure 5 As shown, during use, the through hole 14 on the support plate 13 contains a spiral guide plate 15. When hot air passes through the through hole 14, the guide plate 15 guides the airflow to form a spiral upward airflow, breaking the airflow stratification between layers and making the temperature of the upper and lower layers tend to be consistent.

[0024] This invention, through the setting of a spacing adjustment mechanism, allows the placement position of the support plate 13 to be adjusted according to the height of the edible fungi, such as... Figures 2 to 3 and Figures 5 to 6 As shown, its specific structure is as follows: A rotating rod 16 is rotatably connected to the front center of the support plate 13. A pull rope 17 is wound around the rotating rod 16, and pins 18 are fixed to both ends of the pull rope 17. The pins 18 are slidably disposed in the pin holes 22 on the support plate 13. The mounting end of the pin 18 is fixedly connected to the end of the pull rope 17, and a spring 19 is connected between the mounting end of the pin 18 and the inner wall of the pin hole 22. The actuating end of the pin 18 is used to extend into the slot 20 to achieve a fixed connection between the support plate 13 and the box body 1. The pins 18 form an elastic telescopic structure through the rotating rod 16, the pull rope 17, and the spring 19. The slots 20 are evenly spaced on the left and right side walls of the box body 1. Multiple slots 20 are provided on the left and right side walls of the box body 1 to meet the cultivation needs of edible fungi of different heights.

[0025] During use, when rotating the lever 16, the pull rope 17 pulls the pin 18 to compress the spring 19, causing it to disengage from the slot 20 on the side wall of the box 1. At this time, the support plate 13 separates from the box 1, allowing the height of the support plate 13 to be adjusted. After releasing the lever 16, the spring 19 returns to its original position, pushing the pin 18 to re-engage and fix the position of the support plate 13. The height-adjustable design is suitable for edible fungi at different growth stages, and combined with the airflow dispersion effect of the guide plate 15, it further reduces local temperature deviations.

[0026] In use, this invention utilizes a combination of reciprocating movement of the jet pipe and its back-and-forth oscillation to evenly deliver hot air to the edible mushroom culture vessel on the support plate. The airflow is further diffused by the guide plate, uniformly distributing the temperature inside the chamber. The position of the support plate can be adjusted as needed. Specifically, the slider on the lead screw slides back and forth along the groove. As the slider moves, the gear on the jet pipe intermittently meshes with the rack on the left side wall of the chamber, causing the jet pipe to oscillate synchronously as it moves back and forth. This ensures that the hot air emitted by the jet pipe evenly covers the edible mushroom culture vessel on the support plate, preventing lower temperatures at the corners and balancing the temperature field inside the chamber. A spiral guide plate is built into the through-hole. When hot air passes through the through-hole, the guide plate guides the airflow to form a spiral upward airflow, breaking up the airflow stratification between layers and making the temperature of the upper and lower layers more uniform. When rotating the lever, the pull rope pulls the pin to compress the spring, causing it to disengage from the slot on the inner wall of the box, and then the height of the support plate can be adjusted; after releasing the lever, the spring returns to its original position and pushes the pin to re-engage and fix the position of the support plate. The adjustable height of the support plate is designed to adapt to edible fungi at different growth stages.
